History YMMV / WarriorCats

*** The writers of the film being revealed as Jonathan Aibel and Glenn Berger. Their most well-known past works are the ''WesternAnimation/KungFuPanda'' films, the ''Film/AlvinAndTheChipmunks'' sequels, ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'', ''WesternAnimation/MonstersVsAliens'', and a handful of ''WesternAnimation/KingOfTheHill'' episodes. This raised concerns both about the aforementioned direction they might take since they're comedy (mostly children's comedy) writers, and about the quality of the writing, as most of those credits are generally considered mediocre at best among critics and audiences.

* AudienceAlienatingPremise: The series is about cute, fluffy cats, living in a very violent fantasy 'verse. It has a public, but it's not composed of the small children that could appreciate cute cats in bloody fights but are turned off by the continuity and the complexity of the verse, nor by the older children and teenagers that could be drawn by the fantasy drama but are turned off by the fluffy cats starring it.

** Even if you think Mapleshade was right to kill Ravenwing and Frecklewish, there's no defending how she tried to murder Reedshine, a pregnant woman, for the crime of [[MurderTheHypotenuse being in a relationship with Appledusk]]. Luckily Appledusk jumped in between them and took the blow, but Mapleshade would have moved on to kill Reedshine if it weren't for Perchpaw.

* TheProducerThinksOfEverything: Need a new villain? [[Literature/WarriorCatsTheBrokenCode Bring back a minor antagonist from the third arc and recontextualize him being sent to heaven as an evil plan all orchestrated by him thanks to the error of his ancestors. Oh, and make him ''possess'' Thunderclan's leader too, because he was jealous of him getting with his lover.]] Need a cool power for your protagonist? [[Literature/WarriorCatsPowerOfThree Just say he's good at fighting, so you can make him invincible and also give him a bloodthirsty dark side. Worried about him becoming too overpowered? Just take it from him at the end of the fourth arc.]]

* CommonKnowledge: It's well-known that Ferncloud has had the most number of kits of the series, hence her FanNickname "Kit Machine". That honor, however, goes to Snowbird of [=ShadowClan=], who has nine kits, two more than Ferncloud did. [[note]] Though it's worth noting that the "Kit Machine" nickname originated long before ''A Vision of Shadows'' was released. [[/note]]

** Despite showing up in very few scenes - not getting even a speaking role in his first appearance - Shredtail has achieved a surprising amount of popularity.

** Harestar, for being a NiceGuy, TheAtoner, and a ReasonableAuthorityFigure--especially considering his predecessor Onestar was a huge {{Jerkass}} for three arcs, so having such a calm and kind cat in charge of [=WindClan=] is refreshing.

* FanDislikedExplanation: Fans wondered why Thistleclaw ended up in [[{{Hell}} the Dark Forest]], because while he was an aggressive WarHawk, he technically [[note]]He did order his apprentice to attack and potentially kill Tiny, which would violate the rule that a warrior does not ignore a kit in pain. However, Bluefur intervened and allowed Tiny to escape with only minor injuries.[[/note]] didn't commit any serious crimes in his life - and even the ''attempted murderer'' Ashfur made it to [[{{Heaven}} StarClan]]. Enter the novella ''[[Recap/WarriorCatsSpottedleafsHeart Spottedleaf's Heart]]'', where he was characterized as a pedophile grooming Spottedpaw while also training in the Dark Forest. This made the novella one of the most unpopular works in the entire lengthy series, as most felt that the subject matter wasn't handled well.

* DiagnosedByTheAudience: There are quite a few in this series: Most notably Ashfur, who obviously has ''some'' form of a disorder, if his obsessive pursuit over Squirrelflight is one thing to go by. Throughout [[spoiler: ''The Broken Code'', his internal dialogue in ''A Light in the Mist'', his treatment of other cats, and actually analyzing his personality seems to indicate Ashfur has a very stereotypical form of [[UsefulNotes/PersonalityDisorders a cluster-b personality disorder]], considering he enjoys spreading torment, manipulating, has little regard for others (besides Squirrelflight, obviously), and doesn't appear to feel much remorse over how actually evil he is.]] More icing on the cake is that Ashfur sees ''himself'' as the victim. It's worth noting that these things haven't been confirmed in the books nor by any other sources, but it's certainly a worthwhile thought.
